A new matroid is introduced: this matroid is deÿned starting from any matroid and one of its bases, hence we call it base-matroid. Besides some properties of the base-matroid, a non-trivial algorithm for the solution of the related matroid optimization problem is presented. The new matroid has appli

We consider the problem of finding a minimum weight basis in a matroid satisfying additional conditions which can be described as follows: each element of the matroid is assigned a colour and feasible bases can use at most a prescribed number of elements from each colour. This problem is a special c
